No. 827,400. a

To all whom it may concern:

Be it known that we, SOLOMON L. SHEUER- MAN and JUAN F. HAND, citizens of the United and has for its object to produce an efficient apparatus of. this class which will operate for a considerable time without being clogged, the arrangement of a filter in such manner that it may be readily and thoroughly cleansed without incurring an unnecessary Waste of water, the arrangement of sedimentchambers and partitions separating the chambers, and valves for emptying the sedimentchambers. Q

As regards the chemical process, as also the choice of reagents for the preparation of the 'water and the arrangement of the vessels containing the reagents,'the same are already known and depend in part upon the'charac 'ter of the water and partly upon local causes, and this invention does not relate to same, but solely to the construction of the apparatus.

The chief feature of our invention consists in obtaining an apparatus of any desired form which is provided, by means of partitions, with several chambers, so that the on- Ward movement is thereby retarded and the de osit of sediment is secured.

Tn the drawings, Figures 1 and 2 show a tank or receptacle (designated by the numeral 10) into which leads an inlet-pipe 11, leading from a source of water-supply, the water being impregnated with a reagent before discharging into the tank 11. From the inlet-pipe 11 the fluids, water, and reagent pass into the chamber 12, formed by the pare tition 13, in which chamber 12.the reaction and purification begins. The fiuid passes through underneath partition 13 into the chamber 14, the artition 15 of which directs it in an upward irection to flow through the pipe 16, leading from the top of the chamber 14 to a point near the bottom of the chamber 17 where it is again directed upwardly and through a filter 18 to a pipe 19, whence it is Specification of Letters Patent.

led ofi. In the chambers 12 and 14 because of the movement of the water in vertical directions the heavier chemical combinations are preclpltated and deposit on the upper face of the bottom 20. The bottom 20, as 1 shown, is inverted frustal-shaped; but in our experiments we have found a concaved bottom to operate in substantially the same manner; Hence we do not desire to be understood as limiting ourselves to the construction of the bottom, as shown. A faucet 21 at the lower part of the chambers 12 and 14 allows of the withdrawal of the sediments.

The pipe 16 terminates some distance above the bottom 20 within the chamber 17, which causes the liquid resting beneath it to remain free from 'agltation, and thus secure the deposit in the chamber 17, which may be withdrawn through the faucet 22. The Water passes up through the chamber 17 and through the filter 18, thus completing the reaction, and the purified water passes'into the pipe 19.

The filter 18 comprises perforated plates 23, which rest on supports 24, fixed to the wall of the tank 10 and to the partition 15.

The lates form compartments, the lower one of w ich is filled with excelsior, paper-pulp, Wood fiber, or the like and the u per complartment filled with charcoal, co e, or the cleanse or flush the upper face of the bottom It Will be obvious that when it is desired to.

20 it is only necessary to open the faucets 21 a and 22, the movement of the water being suf-,

ficient to remove the sediment. It will be obvious, further, that when it is desired to cleanse the filter it is necessary only to withdraw enough water from the chamber 17 .tO
